Please choose First Class Postage for this item. There is nothing sleeker than a plain ponytail and this large white rhinestone pony tail holder would add some sparkler. This ponytail barrette is curved and measures 1 1/8th inches at the center tapering to 1/4 inch at the ends. There is a metal catch on the back and no markings. The barrette is in excellent condition with jeweler quality fiery stones.
